STATION-INDICATOR.

sPEoIFIcA'rIoNrormin part of Letters Patent No. 499,895, dated June20,1898. Application filed September 19 1892- Serial No. 44 3 .(N0model-l This invention relates to that class of indi-,

cators which are employed in railway cars and street cars to indicatethe different stations or streets which the car is approaching- Theinvention has for its object certain improvements below described andclaimed, prominent among which is to automatically operate the signal,by means of a lever coming in contact with an inclined projection at theside of the track.

In the drawings forming a part of this specification, Figure 1 is a sideelevation of the indicator mechanism, which in use is fixed in anelevated position upon the wall of the car.

Fig. 2 is the same as Fig. 1, with one side of the frame removed,showing the inside construction. Fig. 3 is an elevation looking againstFigs. 1 and 2 from a point at the right. Fig. 4 is an enlarged sectionalview of lettered details on line 3-3, in Fig. 1, looking Fig. 5 is anelevation of said parts, looking from a point at the right of Fig. 1.Fig. 6 is an enlarged broken view of lettered details fronii'Fig. 3.Fig. 7 is a broken sectional elevation on line 4-4, in Fig. 8, lookingfrom a point at the right, illustrating the mode of operation; and Fig.8 is a section on line 22, in Fig. 7, looking from a point at the left.

Referring to the lettered parts of the drawings, A B. show the sidewalls of the frame, in which the shafts, C D,have bearings, as in Figs.1, 2 and 3.

At E are shown belts, wound upon these shafts O D at each end, whichbelts bear the names of the stations or streets and in theoperationrwind on one shaft and unwind from the other, passing duringsaid operation back of an opening, F, stopping at said opening andpresenting the name of the station or street, as illustrated in Figs. 3and 6 by the words Woodward ave. These belts are made of flexiblematerial, consisting of two strips separated from each other, andattached to each other by means of posts or bolts, 0, leaving a spacebetween said posts for the insertion of cards bearing the names of thestations or streets, as shown in Fig. 6, said cards being passed throughthe slot in the side of the frame, as shown at e, in Fig. 1.

The shafts D and C are provided at one end, outside of the wall, A, withthe gears, G and H. Between these gears G and H is a gear I, meshingtherewith, as illustrated in Figs. 1 and 3. The gears H and I areprovided with ratchets, a and b, and with arms, 0 and e, radiating fromthe axes of said gears. These levers, c and e, are pivotally connectedtogether by a bar, f, Fig. 1. Each of the levers ;c e is provided with apivoted dog, It i, which dogs engage the ratchets a b. The dogs, h 11,are provided with rearward extensions j 7t. vCentrally pivoted to thearm, f, is a rocking lever, m, having elongated slots in each end.

At n is a forked lever, pivoted at 0 to the wall of the frame, A, eachend of said forked lever being loosely inserted in the elongated slotsof the rocking lever, m. The forked lever, n, is provided with a handle,19. The Ohj ect of this rocking lever and the forked lefver connectedtherewith is to reverse the mechanism at each end of the route. trate,referring to Fig. 1, the rocking lever, m, is in such a'position thatthe dog, h, is engaged with the ratchet, a, and the dog,j, is disengagedfrom the ratchet b. When in this condition, (as will clearly appear bythe description of the operating means and the operation hereinafter)the belts, E, will wind on the ends of the shaft 0, and unwind from theshaft D. When the car starts to run in the opposite direction theoperator, by taking hold of the handle, 1), will trip the dogs, causingthe dog j to engage the ratchet b, and the dog h to be disengaged fromthe ratchet a. This is accomplished by bringing the rock- Toillusing-lever, 'n, in contact with the rearward extensions, j and k, ofthe dogs. Motion is first imparted to the shaft 0, and from its gear H,through gears I and G to shaft D. The upper end of the arm f, in Fig. 1,is provided with an elbowed arm, 5, which enters the case,

t, and operates a pneumatic alarm hell, by 100 which wheel 3 comes incontact. with the inelined block, M, at the propertime to indicate thestation or street which the car is approaching. This elbow lever, 2, isconnected with the lever, f, in Fig. 1, by means of a cord, chain orcable, 7'. The end of this cord,chain, or cable rwhich is connected withthe lever 2, is provided with a spring,4 and is attached in an elongatedslot in theend of said lever, as in Figs. 7 and 8. The object of thisspringand elongated slot is to prevent any jar which might be impartedto the indicator 1116011311.

ism by the contact of the wheel 3 with the rail of the track fromoperating said mechanism until the proper.time,.when said wheel willcome in contact with the inclined block, M, at which time the movementof the lever, 2, is sufficient to overcome the yielding eifect of thespring, 4, and operate theindicator.

Just back of the opening, F, to which the name of the station or streetis presented, is a belt-tensioning device, consisting of two rollers,6-6, mounted in aframe, 7, which has end projections passing outthrough'slots, 8,.

in the sides, A B, of the frame, to which pro jections are attachedspiral springs, 9, by means of the bolts, w, the ends of which bolts, w,pass loosely through brackets, T, which brackets areattached to thesides, A B, of the frame. The object of this tensioning-device isindicated in Figs. 1 and 2, it being so placed that its rollers willcome in contact with the A inside of the belts, E E, and bear againstthe.

same with a spring pressure, so as to hold said belts out near theopening, F, where. the names of the stations or streets are presented.

In Fig. 1 an arrangement isshown for presenting rules and regulations ofthe company operating the cars, which consists in an endless belt, S,carried by a roller, having a gear 5 Z, meshing with the gear G. Theinstructions are'on the face of this endless belt and are presented atthe front side (the right hand side in Fig. 1) at the time the stationor street is indicated. This latter device may be employed or not, asdesired in connection with the station and street indicator.

In the operation, when the car approaches a station or street, the wheel3 runs on to the inclined block, M, tripping the lever2 and in turnoperating the lever f, which operates the radial arms, a e, causing thedogs Hz to turn. the shafts C D a distaneeof one space,which distancewould be the width of one of the in-' dicator cards bearing the name ofthe station; l

or street. When the car made its return trip in the other direction, theoperator, by means of the handle, p, would trip'the lever, m, anddisengage the dog it and engage the dog 2' would of course travel in theopposite directioinnaming the stations or streets in the rei verseorderdllning the return. trip. This mechanismfor carrying the belt andfor reversing the direction in which it travels may be used inconnection with any suitable opidea being illustrated. in Fig. 6. r
